The Welsh singer enthused: 'I'm over the moon to be involved in the Doctor Who Christmas Special -
I can't quite believe it as it's a part of the family tradition at the
Jenkins household. I heard the news that I got the role on my 30th
birthday and it was the best birthday present ever.'

Doctor Who writer Stephen Moffat said: 'We're going for broke with this one. It's all your favourite Christmas
movies at once, in an hour, with monsters and the Doctor and a honeymoon
and - oh, you'll see.

'I've honestly never been so excited about writing anything. I was
laughing madly as I typed along to Christmas songs in April. My
neighbours loved it so much they all moved away and set up a website
demanding my execution. But I'm fairly sure they did it ironically.'
